Be it known that l, HENRY il, Barnes, a citizenof the United States,residing at Buffalo, in the county ofJ Futnam andSta-te of lilestvlfirginia, have invented `certain new and useful. improvements inRailroad Crossing Signals, of which the following isv a specification.

This invention relates to railway signals and has special reference tocrossing signals employing a flickering light for night signaling' andan oscillating semaphore blade for day signaling.

One important object of the invention is to improve the generalconstruction of devices of this character.;

A' second important object of the invenY tion is to provide improvedrail supporting means for actuating thesignal upon the passage of`trains.

A third important object of the invention is the provision of meansspecially adapted for ,actuating the signal upon the approach of vatrain onv a single track in either direction.l

llifith the above and other objects in view as will be'hereinaftrapparent, the inventioii coi. s ingeneral of certain novel dctails ofconstruction and combination of parts hereinafter fully described,illustrated in lthe accompanying drawings and specifically claimed.`

In the accoiripanying drawings like characters of" reference indicatelike parts in thesevreral views, and;

Figure 1 is a sideelevation partly broken away showing the sional andits actuating means in relation to a track rail.

Figure 2 is a detail perspective view of a certain rock shaft used inconnection herewith.

Figure 3 is a detail section to an enlarged scale on the line 3-3 ofFigure 1.

Figure et is a similar section on the line 4-4 of Figure 1.

Figure 5 is a detail view looking at one side of the semaphore from thedirection ol' the arrows on the line 5 5 of Figure 1.

Figure 6 is a detail section showing the means for holding the rockshaft in posiw tion to keep the semaphore blade vertical.

In the embodiment of the device here shown there is disclosed a trackrail 10 and a semaphore having a hollow stand 11 and provided at itsupper end with a shaft 12 whereon is fixed a pair of semaphore blades133 and lil, the former being longer than the latter. Supported betweenthese blades on a lamp stand 15 is a lamp 1G. Project ing from thebottom portion of the longer blade is a rock arm 1i' which is connectedby a link 18 witha rock arm 19 connected to a sleeve 20 fixed upon arock shaft 21 supported in suitable bearings, not shown, in the bottomof the stand 11. @n the rock shaft 21 is also mounted a sleeve "7i-omwhich project pairs of arms 23, rollers 24 being revolubly mountedbetween said arms. `Within the hollow Ystand 11 are lugs 25 whichsupport rollers 2G and springs 2T of the coil variety having their endsengaged on the respective rollers 24 and 26 as shown in Figures 2 and 6,these springs acting to hold the arms 23 normally horizontal and thusalso holding the rock arms 19 in horizontal position.

At the inner or track end of the rock shaft 21 there is provided adouble rock arm 28 which normally rests in vertical position and has atits upper and lower ends laterally projecting pins 29. On these pins aremounted the slotted ends 30 or links 31 which pass through guardtubes-or pipes 32 fixed to the inside of the rail 10 by brackets or clipsbrackets the tube or pipe 32 is enlarged as at 34 and these enlargedportions contain pairs of'opposed compression springs 35, said springsbearing at their adjacent ends onf'a collar 36 on the vlink or rod 31.Between other pairs of brackets 33 the rail is cut away as at 37 andpivoted to a block 38 below this cut away portion is a rock arm 39carrying at its upper end a roller i0 located in the gap formed by thecut away of the rail. This arm 39 is guided by a guide bar 41 and therods or links 31 are connected to a strip 12 surrounding the respectivearm 39. It is to be observed that there may be a number of these rollers40 and, as shown in Figure 1, the track arn rangement extends in bothdirections from the semaphore stand. In operation a trainv approachingfrom the right of Figure 1 will engage, with its wheels, the rollers Ll0and this will cause the arms 39 to rock to the left and thus, throughthe rod or link 31, actuate the rock shaft 21 and thereby oscillate thesemaphore blade 13. At night when the lamp is lighted this oscillationwill alternately cover and uncover the lamp thus causing a flickeringthereof. It will be Betweencertain pairs of these i ill) (i ii notedthat, by the peculiar arrangement of the slot end 30 the track apparatuson one side will operate without moving the apparatus of the other sideand that, alter a train passes the semaphore actuating` the trackapparatus beyond the semaphore will not operate the latter.

There has thus been provided a simple and eilicient device of the kinddescribed and for the purpose specified.

It is obvious that minor changes may be made in the form andconstruction ot the invention without departinro)` from the inaterialspirit thereof. lt is not, therefore, desired to com'ine the inventionto the exact form herein shown and described, but it is desired toinclude all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

l. The combination with a semaphore stand and its blade; of railroadtrack, and track supported means for repeatedly oscillating said bladeincluding a rock shatt having operative connection to said blade andhaving a rock arm at one end, a rod having a pin and slot connection tosaid rock arm and supported adjacent a track rail, and a plurality oflevers each pivotally connected to said rail and projecting thereabovefor engagement by the Wheels of a train, said levers each beingconnected intermediate its ends to the rod.

2. The combination with a semaphore stand and. its blade, of railroadtrack, and

`track supported means il'or repeatedly oscilating said blade includinga rock shaft iav'- ingoperative connection to said blade and having arock arm at one end, a rod having a pin and slot connection to said`rock arm and supported adjacent a track rail, a plurality of leverseach pivotally connected to said rail and projecting' thereabove forengagement by the wheels of a train, said levers each being connectedintermediate its ends to the rod, and spring means normally holding saidrod in position to elevate the vfheel engaged ends 0i" the levers.

3. The combination with a semaphore stand and its blade; oi railroadtrack, and track supported means for repeatedly oscillating' said bladeincluding' a rock shalt having` operative connection to said blade andhaving a rock arm at one end, a rod having a pin and slot connection tosaid rock arm and supported adjacent a track rail, a plurality of leverseach pivotall;Y connected to said rail and projecting thereabove forengagement by the wheels of a train, said levers each being connectedintermediate its ends to the rod, spring means normally holding' saidrod in position to elevate the wheel engaged ends of the levers, andother spring means normally holding` the semaphore blade in verticalposition,

l. In combination, a track rail, a semaphore stand adjacent said rail, ashaft in the upper parlJ of said stand extending' transversely thereof',a blade iiXed on said shaft, spring means normally holding said bladeraised in vertical position, a rock shaft extending,` between the railand stand, corresponding rock arms on said shafts, a link connecting;said rock arms, a double rock arm on the end of the shaft adjacent therail pins projecting' from said double rock arm adjacent its ends, rodssupported from said rail and extending' in opposite directions from therock shaft, slotted ends on said rods engaging' said pins, levers foreach rod each having` its lower end pivotally connected with the railand having its upper end provided with a roller projecting above therail head said levers each being connected intermediate its ends to arespective rod, and spring means normally holdingr said levers invertical position.

In testimony whereof I aiiiX my signature.
